WebDec 17, 2024 · The relationship between strain and stress is described by the material’s stress-strain curve. Figure 1 shows typical stress-strain curves from a polymer thermoplastic material and thermoset rubber material. Both the materials have plastic strain properties where when the material is stretched beyond the elastic limit there is some … Web3 without measuring the cross-sectional area of the specimen during the tensile experiment, the “true” stress-strain curve could still be constructed by assuming that the volume of the material stays the same. Using this concept, both the true stress (σ T) and the true strain (ε T) could be calculated using Equation 3 and Equation 4 respectively.The derivation of …
WebThermoforming involves stretching of rubbery solid plastic sheet. For many polymers, the stress-strain curve is not linear, but is curved. The room temperature modulus for LDPE, for example, is oven in Modern Plastics Encyclopedia as 25,000 to 41,000 psi. Webcould be calculated from stress-strain curves. – This number can also be estimated from the extent of swelling. The larger n, the lower the extent of swelling. Swelling is the …
